In the case of JIS Flame proof (/JF1), specify JIS G1/2 female for electrical connection and also specify in the option code with Flameproof

packing adapter (PG5) for the cable wire construction.

TIIS is the abbreviation of Technology Institution of Industrial Safety

The JIS G1/2 female is not applicable for electrical connection.

• In case of specifying JIS Flameproof Explosion proof type, JIS G1/2 female is applied for wiring connection.

• Specify in the option code with Flame proof packing ground (/PG5) for the cable wire construction.

In case of specifying FM explosion proof type, ANSI 1/2 NPT female is applied for wiring connection.

In case of specifying CENELEC explosion proof type, ANSI 1/2 NPT female, DIN Pg 13.5female or ISO M20ϫ1.5 female is applied for

wiring connection.

In case of specifying CSA explosion proof type, ANSI 1/2 NPT female is applied for wiring connection.

There is a case that a little calibration water should stay in the meter tube. So this is not degrease treatment in strict sense.

When this option is chosen, the output is set at low level (3.6 mA) when burn-out. Otherwise is set at over high level (21.6 mA) at shipping.

Model UYF202J (25 mm), UYF215J (150mm), UYF220J (200mm) is not applicable.
